[Q]bricked Huawei Ascend P1

hi, i have a problem with my p1.
i tried to flash a rom nut something went wrong and it bricked. the preblem is that i have the stock recovery that don't allow to install new roms nor restore backups. the other problem is that i cannot acces bootloader (holding volume- and main button and release the main then it vibrates) to connect the smartphone to the pc, install drivers and emulate the cwm.
what can i do?

If you are installing drives, you are probably using windows. I am not familiar about windows, but I played a lot with this device and I never got it bricked.
You can boot to bootloader just with vol- and power button, when the phone vibrates, you can release the power button and still hold the vol- button for some extra seconds (maybe 10 is enough). Then plug the phone to the PC and try `fastboot devices`. If you can see there you devices, you can than flash the recovery you will need, however if you cannot find here your device, your drivers are not installed correctly or your device is definitley bricked.

You wrote, that you have a stock recovery. You are able to get there? Do you know which firware revision you have installed before it got broken?
If you know the revision, you can choose your version or a higher version from this thread http://forum.xda-developers.com/showthread.php?p=40901091#post40901091, put the UPDATE.APP to [SDCARD]/dload/UPDATE.APP and try to flash. Power off the phone, than press both vol- and vol+ buttons, press power button and when the phone vibrates, you can release the power button. The stock recovery should flash your update, or it will complains about version. If you are in this stage, I think your phone is not bricked.

thanx i didn't get that the bootloader was the logo... i thought that it was an option screen like the recovery -.-
and it didn't let me install drivers until i opened Hisuite with admin privileges.
thanx anyway!

entering recovery on f400s

I would like to know if someone has the same problems as me entering recovery mode on lg g3 f400 korean series
according to many sites, by pushing volume down and power simultaneously until logo let go for one second and repush same buttons again until the factory reset screen.
THAT IS GREAT. but for the life of me and after trying 2 and half trillion times, i am coming zero for 2 and half trillion times.
can someone tell me EXACTLY the proper sequence. it is exhausting not to succeed at something that apparently is so simple.
thanks guys
happy new year, if you're in a country that celebrates it.

Try this (bit different ): Push Power + Volume down, when LG Logo appears release power button only for 1 sec but keep holding Volume down, then push power button again. Keep holding those 2 until you enter recovery(Hopefully).

tried
i tried exactly 20 times, pressing 2 buttons, releasing power then pressing it right after logo pops.
nothing doing less than 3 seconds after releasing, the led starts flashing at the begining of the load program and that's when i start crying

Can you turn on the device and enter your OS? If so and you just want to enter recovery, you can download an app that can make you boot into recovery like Quick Boot ( Reboot ) . You need to be rooted though. Sorry can't come up with anything else.

reason why i am asking
your idea is good, but i want to upgrade to android 5.0. = what happens is once you upgrade there is not a single app that lets boot into recovery that does not require root.
so i download the app, but since my android upgrade has erased the previous root, in urder to flash the superuser file app i must do it FROM RECOVERY
if i found an app that lets go into restore WITHOUT ROOT that would be fantastic. but i don't know of any,
if you do, please pass it along, that's all i need.
thanks, sincerelyh

If you want to upgrade to Official LG Stock Lollipop you can use LG Flash Tool 2014 and the Right KDZ for F400S, that way it will probably fix your "broken" Recovery. You don't have to enter Recovery for it, you have to enter Download mode ( Turn off device, connect usb to Computer then plug usb to G3 while pressing Volume UP button ).
Guide and links: http://forum.xda-developers.com/showthread.php?t=2785089
Stock Lollipop KDZ for F400S : http://storagecow.eu/Xda/LG G3/Stock/Lollipop 5.0/Lollipop_F400S.kdz
Give it a go.

did you find a remedy ? or can somebody else help?
whats proper way to enter recovery on LG G3 Korean F400S
If the OP is doing the right hardware key combination, and not getting recovery mode, is recovery (stock recovery) missing from his phone altogether? Is that a possible thing?

I for the life of me cannot find the steps on the internet for this but I did find them and entered recovery once before.
The steps for entering recovery for the F400 variants is DIFFERENT than the typical G3's out there.
I found a site that listed 3 different hardware key combinations and can't freaking remember what they were!!!!
If I find it I will post back here...I can't believe the steps aren't in a sticky somewhere

Power + volume up till you see the LG logo
Release both and immediately Volume up + Volume down
Woo!!!

I had a similar issue but was able to get into recovery mode and restore a backup.
Can you get to recovery like this
Power Down the LG G4
When Off, Press and Hold the Volume Down and Power Buttons at the Same Time
Continue Holding These Two Buttons Until You See the LG Logo
When You See the LG Logo, Let Go of the Volume Down and Power Buttons for 1 Second
After 1 Second has Passed, Immediately Start Holding the Power and Volume Down Buttons Again
Continue Holding These Two Buttons Until You Boot Up into the LG G4 Recovery Mode

Hi I'm sorry if you've already said you can't get into recovery mode or anything but when i bricked my g4 i used the lg flash tool to flash h815 10c stock and then instead of flashing the latest twrp (the blue themed one) i flashed the one before it which is 2.8.6.1 and it worked perfectly so if you manage to get into recovery or fastboot then try and flash that version of twrp instead , good luck buddy...

How did you "brick" (it's not) it? Kill switch is an anti theft feature, usually triggered remotely by the user.

This button combo you posted is wrong any way...you only release power for 1 sec and continue holding vol down and the re press power

I cut and pasted those instructions from another site. They held me back from fixing my phone for hours until I discovered the method you have mentioned. I haven't seen any site that tells us to do it like you said, I just was trying different ways and then hey presto!! it worked.

Try to take out the battery. After put it back and press the volume up and plug in a the lg micro USB to your phone but before doing that be sure it is plug in to your computer and wait until you see the download mode. I forgot the video link but just search up unbrick,unroot lg g3 on YouTube and search for the video that you see a lg g3 with a blue screen and a number 3 in the middle. After you find the video use it to guide your self to repair your lg g3. Hopes it helps please message me back if you do it and if you what I can help if it doesn't help.

I hope you know to enter download mode your phone has to be off. The while holding the volume up button you connect your phone to your usb. It wont even show u an lg logo if that fails you try with volume down. If that fails then you will have to short circuit the phone

I was able enter download mode before I used that tool..now it just keep on bootlooping.
I think I have to try short circuit as u recommend.
Thanks for the help.
